GUS-QS8B-03-1151-B Description

The GUS-QS8B-03-1151-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP-packaged device integrates 15 resistors with a 1.15KΩ resistance value, offering an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 100V maximum voltage, it operates reliably across a -70°C to +125°C temperature range. The gull-wing termination ensures robust solderability, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.

GUS-QS8B-03-1151-B Features

• Precision Performance: Thin-film technology delivers 0.1% tolerance and ±25ppm/°C TCR, ideal for signal conditioning and analog circuits.
• Robust Construction: QSOP package with gull-wing leads enhances mechanical stability and thermal dissipation.
• High Power Handling: 0.05W per resistor (0.75W total) supports distributed power loads in dense layouts.
• Wide Temperature Range: Operates from -70°C to +125°C, suitable for industrial and automotive-grade environments (though not PPAP/automotive-certified).
• Strict Dimensional Tolerances: Tight ±0.1mm height/length and ±0.2mm depth tolerances ensure consistent PCB assembly.
